WebNov 21, 2024 · 10. Method 3: Using bit mask. To set a bit, we can take OR of 1 and that bit (as 1 1 = 1, and 1 0 = 1). Therefore, to set all odd bits of an n-bit number, we need to use a bit mask which is an n-bit binary number with all odd bits set. This mask can be generated in 1 step using the formula of sum of a geometric progression, as an n bit ... WebJan 27, 2024 · std:: bitset. The class template bitset represents a fixed-size sequence of N bits. Bitsets can be manipulated by standard logic operators and converted to and from strings and integers. For the purpose of the string representation and of naming directions for shift operations, the sequence is thought of as having its lowest indexed elements at ...

Web4. Try this: #include unsigned int bits_per_byte = CHAR_BIT; unsigned int bits_per_integer = CHAR_BIT * sizeof (int); The identifier CHAR_BIT represents the number of bits in a char. The sizeof returns the number of char locations occupied by the integer. Multiplying them gives us the number of bits for an integer. WebDec 22, 2015 · The obvious way to do 1 is to generate a mask ((1<<(pos+1)) -1) and & it. A more efficient way is to left-shift by 63-pos, leaving the bits you want packed at the top of a register.. This also has the interesting side-effect of putting the bit you want to test as the top bit in the register.
